Scoring for all the documents in the index relative to a query
|
|
Hi everyone,
I am trying to obtain the score for each document in the index relative to a given query. For example, if I have the query "search file", I am trying to get the list of all documents in the index and their scores relative to the given query. I tried first using Hits, which gave me the normalized score. I thought that I don't see the whole list of documents and their scores because of the normalization, so I tried using HitsCollector. But even after using HitsCollector, I get the same number of matching documents, so the normalization didn't exclude documents because of negative scoring. Does Lucene actually compute the score for all the documents in the index or just for matching documents? I really need to have the scores for all the documents in the index relative to the query (even if negative), not just the ones that contain the query terms(this is what Lucene considers "matching documents", right?). Is this possible using Lucene?
I really appreciate your time and effort!
Thanks,
Sonia
